Prosecutors say O'Neal was on drugs Aug. 2 when he veered into oncoming traffic and collided with another vehicle in San Diego County.

Defense attorney Heather Boxeth said at a previous hearing that her client had been trying to help his half-brother Redmond O'Neal, who had been arrested on suspicion of heroin possession the same day.
